While we can't exactly call it Cards Against Humanity (they're a bit picky about that), there's a new game out for Android that works with your Chromecast to let you play basically-Cards-Against-Humanity with your friends, and it's called Cardcast. Cardcast allows you to create decks, download decks (including most of the official CAH decks), and all you need to play it are some friends, a Chromecast, and an Android device for each player.
